2 Claims. (01. 111-16) This invention relates generally to seed planters. More specifically, the invention relates to a power check mechanism for a seed planter adapted to be operated automatically from a suitable draft device such, for example, as a tractor.

It is an object of the present invention to providea seeder' which operates automatically to drop seed at intervals as the seeder is drawn over the ground.

Another object is the provision of a power check for a seed planter which automatically operates to drop seed at regular intervals and which is adjustable in order that the planted rows will be aligned both longitudinally and transversely. V

A further object is to provide a seed planter of the aforedescribed'character which will be rendered inoperative during the interval required for turning from a seeded row to an unseeded row.

Additional objects and advantages of the present invention are those residing in and relating to the novel construction and arrangement of the parts thereof as will more clearly appear as the description proceeds, reference being had to the accompanying drawings of which:

Figure 1 is a top plan view of the seeder of the present invention according to the preferred em.-

bodiment thereof;

Figure 2 is aside elevation of the seeder;

Figure 3 is a detailed view of a portion of the check mechanism, and

Figure 4 is a sectional view taken substantially along the line H of Figure 2.

Referring now to the drawings for a clearer understanding of the invention, thereis shown thereon a portion of a suitable draft device such, for example, as a tractor. The numeral ill desig nates a tractor wheel journaled to axle i i. Secured to the draft bar 112 of the tractor is a draw bar i3 which in turn is secured to a portable An adjustable, circular steel plate i5 having a hole It cut radially therein is disposed about the axle II and is maintained in an adjusted position with respect to the tractor wheel ill by a spring pin ll adapted to fit selectively into recesses l8. Disposed intermediate the wheel ill and plate It and secured to the wheel is a base plate l8 in a Circumferentially mounted on the circular plate It and arranged in predetermined spaced relation thereon are a plurality of steel pins 2! adapted successively to engage an inclined, slidin a counter-clockwise direction, the shaft 29 being rotatably secured to the seeder framework it in any suitable manner. The lower end of the vertically inclined arm 28 is pivoted to .a knee joint 32 and operatively secured to the square shaft 29. Bracing arms- 33 extend from. the seeder frame and support a ball socket bearing 34.

Amxedto the draw bar M are two angle irons '35 and as which support a slide hearing 31 through which extends a curved shaft 38, one

' end of the shaft being fixed to the rod 22 through seeder frame indicated generally by the numeral peripheral portion of which is formed the circumferentially spaced recesses I8 which permit adjustment of plate it, a collar l9 being fixed to axle I i in order to maintain the plate I5 in a predetermined position on the axle.

bearing 23. The other end oi shaft 38 is pivotally secured to a connecting link 89, which link in turn is pivotally secured to a link member I rotatable by motion of a lever e2 operatively secured thereto.

In operation, the rod 22 is urged'rearwardly as the pins 2i momentarily move into engagement therewith. As rod 22 moves rearwardly, motion is transmitted through connecting joint 26 to the vertically inclined arm 26 thereby causing the square shaft to rotate in a counter-clockwise direction and initiate the operation of the respective lime and seed hopper mechanisms to drop lime and seed through valves 3 l. The purpose, of course. for the lime hopper is to mark the position of the seed check for future reference. Any suitable means (not shown) may be employed for restoring the square shaft to its initial position and the rod into operative relation with the pins 2i, such.rneans may take the form of resilient biasing means for the shaft.

murder to prevent the pins from engaging rod 22 while the tractor is turning, lever 42 is onerated to place the rod in an inoperative position with respect to the tractor wheel and pins, such position being shown in dashed outline in Figure 1. It will be understood of course that. movesocket bearings 2i and 34, the arm 26 being movable in one direction through the knee joint 12.

As mentioned heretofore, the circular plate l5. carrying the pins 2| is rotatable by removing the spring pin II from engagement with one of the recesses it. Such a condition is desirable in order to align the checks in each row to be seeded. By selecting one-of the recesses 18' to receive the pin I1, the instant position of rod 22 with respect to the next engaging pln'may be varied whereby the position of the first check in any one row is controlled.

From the foregoing it should now be apparent that a power check for a seed planting device has been provided which is well adapted to fulfill the aforesaid objects of the invention.

While the invention has been described with particularity in reference to an example thereof which gives satisfactory results, it readily will be apparent to those skilled in the -art to which the invention pertains, after understanding the invention, that further embodiments, modifications and changes may be made therein without departing from the spirit and scope thereof as defined'by the claims appended hereto.

What is claimed as new and desired to be secured by Letters Patent of the United States is:

1. The combination with a tractor, a plurality of pins circumferentlally arranged on one of the tractor wheels and rotatable therewith, a

4 ing said rod and said shaft for rotating the shaft when the rod is moved rearwardly, and means for moving said rod out of operative relation with said pins thereby displacing said longitudinal axis of the rod from the axis of rotation of said pins.

2. The combination with a tractor, a plurality of pins circumferentiaily arranged in predetermined spaced relation on one of the tractor wheels and rotatable therewith, a portable framework secured to said tractor, a slidable rod mounted on said framework in operative relation with said pins and having a longitudinal axis disposed in the axis of rotation thereof, said rod being adapted to be engaged successively by each of said pins and to be moved rearwardly thereby as the tractor wheel rotates, a seed hopportable framework secured to said tractor, a

.per supported on said framework, a pivotally mounted shaft for operating said hopper, means interconnecting said rod and shaft for rotating the'shaft eachtime the rod is moved rearwardly, means for moving said rod out of operative relation with said pins thereby displacing the longitudinai axis of the rod from the axis of rotation of said pins, and mean for varying the instant position of said plug with respect to said rod.
